中文摘要：
随着海上风电的迅速发展,海上风电场内部电气系统设计受到广泛关注。针对目前较常用的放射形布局,从开关配置的角度对其经济性进行研究,在传统开关配置方案基础上提出了开关完全配置方案和开关部分配置方案,并在综合考虑了投资成本和由于海底电缆故障引起的故障机会成本2个因素后,对上述3种开关配置方案的总成本进行评估,对影响总成本的开关设备价格、电缆故障率和故障维修时间等进行了灵敏度分析。分析结果表明,从经济性角度考虑,开关部分配置方案是3种开关配置方案中的最优选择。
英文摘要：
Along with the rapid development of offshore wind farms, the internal electric system of them has caused wide public concern. In this paper the economy of switchgear configuration for offshore wind farms is researched and based on traditional switchgear configuration the switchgear complete configuration and the switchgear partial configuration are put forward respectively; after the comprehensive consideration of two factors, i.e., the cost of investment and the fault opportunity cost due to the fault of submarine cable, the total costs of above-mentioned three switchgear configuration are assessed, and the sensitivity analysis on such factors impacting total cost as the price of switchgear, cable failure rate and maintenance time of failure is performed. Analysis results show that considering the economy, the switchgear partial configuration is the best one in the three switchgear configurations.
